the previously,.usedffspindlebases, as above described, Aby providinganew form of base, tha-,characteristics andy y,salient Ifeatures offwhich are" described in the following ,speciii cation with-g reference.to the :drawings Aherewith ligiirnished, inlfwhich Ifhave yillustratedthe preferred l. embodiment? 'of vfthe `ir'ivention as applied to a ballbearingl spindle. The invention consists in the novel characteristicsoit such base, and the combination thereof with a spindle blade and itswhirl, hereinafter Il ully described and claimed.

ln the dra-wings,-

Fig. l is a sectional view ot a complete spindle including` a base inwhich the present invention is embodied, a blade, a. driving whirl it'orthe blade, a stop pin and a cover plate; i p

Fig. El is a. plan view of the base;

lllig. 3 is a plan view ot the cover plate; and

`Figi it is a vertical cross section of the cover plate.

Lilie reference characters designate the same parts wherever lthey occurin all the ligures. j

a, represents thebase, b the blade, and c the whirl applied to theblade. The base is provided with a lateral flange d. by which it restsonthe spindle carrying rail ot the spin ningr frame, the lower part ojlithe base proj ccting through the rail. being' screw threaded in the parte to receive a nut :for clamping it to the rail in the usual way. Theinterior ot the base is drilled to torni an internal chamber or socket fto receive the foot of the blade and a step bearing g. j In the presentdesign, the upper part of the base is enlarged to receive a sleeve la.forming; lthe outer race of a ball bearing e', ojt the characterdescribed in my prior appli fation, Serial No. 750,212, previouslyreit'erred to; but this is a ldetailwhich may be t'leparttal from; andthe essential characteristics ot the invention may be applied to thebase adapted for a spindle of the common ji1urnalfbearing type. Theproportions of the spindle blade. base and whirl, and the relation oitthe whirl to the tlang'e, are, or may be, substantially the same asthose eXist ing' in spindles ot the type and designs now in generalconnnercial use, except that the tlange extends at one side ot' thespindle to a much greater distance than is usual with sueh spindles.

ln the upper horizontal side of the flange (Z is an open pocket j toreceive oil, and from the inner' vall oi this pocket; a hole leads tothe chamber f. The pocket and the outer boundary olf the flange arepreferably concentric with the blade, as shown in plan view by Fig. i2.As previously7 stated, the flange Z projects at one side of the spindleto a much greater distance than usual hereto'lore, and the part soprojecting' is that in which the oil pocketis contained. It extends so:tar that the pocket is entirely outside ot the circumterence ot thewhirl, or, in other words, .it is farther away from the axis oit thespindle blade than the circumference of the whirl. Then the spindle isapplied to the spinning rail of the spindle frame, the base is set withthe oil pocket on the outside or front, (considering, as the front theside ot the spindle, at which the attendant stands when oiling it orperforming other duties in corner-tion with the machine). The sides oitthe base toward adjacent spindles may be flattened. as shown in Fig. 2,in order to permit placement ot spindles as near together as permittedby other factors, and the oil pocket may he as long as the distancebetween these sides less the space needed to provide contininnf walls atthe ends of' the pocket.

The hase provided at the rear with. a luar Z to support a pivot pin m.by which a plate o is connected to the base. The plate o serves as acover :tor the oil pocket and also as a holder for a stop pin perdoti'er guard; having a rear extension q in which'the pin is mounted.The central part ot the plate is open, or formed with an aperture, toadmit the risingy part' oit the base, which provides the hearing for theblade, and the spindle whirl. The rear part o'l.z the aperture.designated as i' in Fig. il, is complemental to the lug' Z. andelsewhere the aperture is large, enough to permit the plate, whenraised, lo clear the lower flange of the whirl and to be raised highenough to fully uncover the pocket, as shown bydotted lines in Fig. l,giving' a clear `view of it to the attendant and leaving1 ampleroom forpouring oil into it. The forward part oi theplate is of properdimensions to overlie and 'tully cover the oil pocket j and to extend atits outer rim somewhat beyond the adjacent part of the base. itlange tl.j j

The stop pin y) rises from the cover plate at. the rear ot thewhirtavhere it otlei's no impediment to tying and applying the drivine'band, and its upper end is bent over so as to overlie the upper flangethereof and prevent the bladebeing renioved 'from the base when thebobbin dotted. But when it is necessary to remove the hladegthe stop pincan be shifted out oil. the way of the whirl by slightly raising!` the'forward side ot the plate.

In calling' the member o a plate, l have not intended to impl;Y alimitation as to its torni. In its jfu'eierred torni, as here shown, itcon'lpletely surrounds the anis ol` the spindle. but it may be otherwiseformed. That part. ol it which lies at the 'tront of the hase and coversthe oil pocket is olf short height or thickness and substantially flaton the upper side. The upper surface ol. the plate. as to this part. isthus located at a substantial distance below the bottom of the whirl,and leaves an open unobstructed space in which the risingpart of thebase above the` llanee is exposed. j

The part which l have just designated as the rising,lr part ot the baseis the part which receives and surrounds the sleeve 7b, pre* Muev'iously mentioned, and. is surrounded `at rits Vzend the lower hparteiitlie Whirl. It provides a stationary surface'gexposed at the front side.of thespindle, over :which the endsxoit .the drivingb'and may :be'passed and A'against@which the :band may be .-su'p vported While :theseyends are '.tifedtogether,

' Wherefore flthis part of :theflbase may be termed 1a. :band:suppe-rit. This 'band support is approximately equal 1in radiusto lthe:bottom of ythe yband. receiving groove 1in ,the whirhithus'enabling aband vto be :tied "with y suicienttensionifor:drivingthe'ivhirh Tihematerial used lfor driving !"bands is suiiiciently :elastic toy vpermitthe band, after Ibeing so tied, toghe passed 'over the outstanding3lower flange ot'V the wlifi-r'l. This band f support -enables thedriving :band fot :any

spindle to be tied `without stopping the entire spinning frame'in whichthe spindle is mounted, since the stationary fsurface 'of the support.enables .the operatorto hold the band stationary @while tying. theknot, even thoiwli fthe driving drum, :around whichfrthebandnfallsofpasses, continues Vin rotation.l

The same support als'oserves as a means tor temporarily holding .theband .when .the

- blade and whirl are removed Vfor itu-rniiig no y the band todr'ive.the spindle-inthe opposite direction. Its presence in all` thevspindles of a spinning :trame greatly facilitates, and

'shortens the time necessary l"for, changingA the bands to driveA allthe spindles oppositelyy to their previous direction of rotation.`

It will be understood from the" foregoing description that the base canybe cast in a vertical position, for it has no projections Which wouldprevent drawing of the pattern from either part of thesandmold in alongitudinal direction. This allows thev heavier metalloids ot' themolten iron to settle symmetrically around the axis of the base vandenables the subsequent drilling the spout of his oilv can to the mouthofthe Oil stem in the prior type spindle.V Thel danger of overilling thepocket is largely avoided,4 because the' attendant, byV noting when theoil ceases `to drain out of the pocket as he pours it in, and beginstolill f up, can tell that the interior of the base is full of oil, intime'to cease pouring before he has overtilled the pocket. kSuch oil. as
